Hi All,

We have a mix of i686 and x86_64 SLES9 nodes, some with IB interfaces
and some without. Ideally, we want users to be able to run the same
binary on any node. Can I build a common OpenMPI for both platforms that
will work with either 32 or 64 bit IB drivers (Topspin)? Or do I have to
use all 32bit IB drivers? Any advice is appreciated.
